CVE-2022-50819

In the Linux kernel, the following vulnerability has been resolved: udmabuf: Set ubuf-sg = NULL if the creation of sg table fails When userspace tries to map the dmabuf and if for some reason e.g. OOM the creation of the sg table fails, ubuf-sg needs to be set to NULL. Otherwise, when the userspa...

kernel: udmabuf: Set ubuf->sg = NULL if the creation of sg table fails

A flaw was found in the Linux kernel’s udmabuf subsystem where the scatter-gather sg pointer was not properly set to NULL if creation of the sg table failed. If userspace attempts to map a dmabuf and the sg table allocation fails e.g., due to memory exhaustion, the kernel later attempts to free a...
